Cape Town - Australia all-rounder Marcus Stoinis revealed it will be a "massive boost" to have David Warner and Steve Smith back in the national squad for the Cricket World Cup, which gets underway next month.

Smith and Warner, former captain and vice-captain of the Aussies, were both included in Australia's 15-man World Cup squad for the tournament that starts in England on May 30.

The global showpiece will mark the return to international cricket for the duo after both were given one-year bans for their part in the ball-tampering scandal that took place in South Africa.

Australia have also hit form as a team just at the right time after they beat India and Pakistan in ODI series away from home in recent months and Stoinis feels it bodes well for the upcoming tournament.

When asked about the return of Smith and Warner, Stoinis said in quotes published on : "It's a massive boost.

"Also the fact that people stepped up in the last three-four months and we started winning games consistently.

"It all adds to the mix and hopefully, it adds to a World Cup-winning combination."

Australia open their World Cup campaign on June 1 when they take on Afghanistan in Bristol.
